It was about 20 cm long.
Dead on the road, but didn't look particularly flat/squashed.
Endangered species (re)introduction. No historic records from Marin County, but historic range includes Mendocino County down to San Bernadino. Historic occurrence closest to this location is Presidio near Fort Point.

In the backyard of a home formerly occupied by the caretaker of Laurel Hill Cemetery. Likely an ornamental cultivar, but possibly a species that occurred within the former cemetery grounds (which also featured the Franciscan and Raven's manzanitas). According to Tom Parker, possibly a subspecies of Arctostaphylos bakeri.
Visiting almost every flower in the area, but in this photo resting on the non-native Everlasting Pea (Lathyrus latifolius).

Ceanothus thyrsiflorus was reported to have covered many of San Francisco's hills at the time of the Gold Rush, but its chaparral and coastal scrub habitats were quickly decimated by wood cutters gathering firewood to supply a growing city (one with relatively few trees other than coast live oak). Blue blossom is now abundant in San Francisco only on the Presidio Coastal Bluffs. This lone individual is at the top of "Dead Man's Bluff", and has likely escaped trampling due to its location at the very top edge of the highest cliff at Lands End.
In a drainage filled with concrete and other debris, and mixed in with iceplant (Carpobrotus edulis).
On steep eroding bluffs. Currently in fruit.
Growing along a remnant of the old railroad grade near Dead Mans Bluff. Smaller petals & leaves, and late-blooming compared to typical Grindelia hirsutula; fits general appearance of G. hirsutula var. maritima (a rare taxon) which is no longer recognized by The Jepson Manual.
Growing on a steep north-facing slope near Dead Man's Bluff. Photo is blurry due to its dangerous location.
The one and only vouchered Lands End collection for this locally uncommon species dates from 1931.
